Hydraulic Cylinder Components & Custom Shafts | DREJEX

Question 1

What is your maximum machining capacity for heavy components?

Accepted Answer

Powered by our 6140 and 6150 series CNC lathes, we can turn large-diameter components up to Ø500mm. This makes our facility perfectly equipped for heavy-duty hydraulic cylinder barrels, large glands, and oversized transmission shafts.

Question 2

What tolerances and surface finishes do you consistently hold?

Accepted Answer

For critical dimensions like bearing fits or hydraulic seal grooves, we routinely hold H7 tolerances. By utilizing precision centerless grinding, we achieve surface finishes down to Ra 0.4, ensuring zero-leakage performance and extended seal life.

Question 3

Do you handle secondary operations like heat treatment and plating?

Accepted Answer

Yes. Core CNC turning and grinding are strictly kept in-house at DREJEX. For secondary processes like induction hardening, Q+T, and Hard Chrome Plating (essential for our piston rods), we work with a tight network of certified local facilities. We manage the logistics and take 100% responsibility for the final quality.

Question 4

How do you guarantee the quality matches my exact blueprints?

Accepted Answer

We rely on hard data, not guesswork. Every batch goes through rigorous first-article inspection and final CMM checks. We don't just ship parts; we ship confidence.

Question 5

Can you provide material certificates for the parts?

Accepted Answer

Absolutely. We know material traceability is non-negotiable for fluid power and drive systems. We provide original Material Test Certificates (MTC) and detailed dimensional inspection reports with every shipment.

Question 6

What is your Minimum Order Quantity (MOQ)?

Accepted Answer

As your custom machining partner, we are flexible. We efficiently handle mid-to-high volume production runs (500+ pcs), but we are also perfectly set up to run smaller batches (20-100 pcs) for specialized heavy machinery replacements or prototype validation.

Question 7

What are your standard lead times for custom machined parts?

Accepted Answer

It strictly depends on the batch size and material availability. For components machined from in-stock bar stock, we can expedite samples and initial low-volume runs within 10 to 15 days. Larger production runs or parts requiring custom forgings typically take 4 to 5 weeks. We will provide a guaranteed delivery date alongside your quote.

Question 8

Why are your subcontracting rates so competitive?

Accepted Answer

Because you are paying direct-to-factory. We operate with a lean structure and zero bloated marketing overhead. Your budget goes entirely into raw materials, machining time, and quality assurance.

Question 9

How do you protect my intellectual property and custom designs?

Accepted Answer

As a dedicated subcontractor, your IP is completely safe with us. We routinely sign and strictly adhere to Non-Disclosure Agreements (NDAs). Your proprietary blueprints, 3D models, and part applications are kept strictly confidential and are never shared, repurposed, or showcased to third parties.

Question 10

How do you package heavy shafts and cylinders to prevent rust and damage?

Accepted Answer

Heavy precision parts require robust protection. We apply premium rust-preventative oils, individually wrap critical ground surfaces, and pack everything in custom-built, fumigated wooden crates engineered for secure global sea or air freight.
